"We start shooting soon and we just got the script a few days ago, so that's exciting," Nikki revealed. "They really do capture the essence of the books and the story and they're very faithful, and I think what the studio, as well as the actors and the writers, have all sort of realized is that's the success of this, the origin [a.k.a Stephenie's source material] is obviously where the success came from," she said. "So we would be sort of silly to stray away from that."

"I have to say that in 'Breaking Dawn,' Jacob and Rosalie have an especially... their relationship is pretty unique," she said with a smile. (Fans of the book know that Rosalie and Jacob have a few very heated interactions regarding the birth of Renesmee.) "It's quite entertaining."
